Dell power manager error 1720 pro#
When you get a chance and if you have a good copy of XP Pro lying around, check out UBCD for Windows ( ). One last idea, in line with your thought process of using a live CD. I have found that over the years I have started skipping the easy fixes and jump strait into the OS blame game only to find that the cable end had one wire that was not touching causing it to go nuts.Īnyway. Thanks for the input so far, much appreciated. XP isn't reporting any hardware errors, and as I said before loopback pinging works fine. That's why I'm convinced it's a problem with the NIC, either a hardware problem or a configuration problem. I've tried resetting the switch numerous times, swapping cables between the laptops, changing ports, and also plugging the faulty laptop directly into the router via the Ethernet wall socket. The other laptop is working fine (in fact it's what I'm using to post this). The way my desk is set up is that I have two laptops connected to a dumb Linksys 8-port switch and this is connected directly to the router via an Ethernet wall socket. I just ran the 'netsh int ip reset resetlog.txt' command again and still the same problem. I'd already tried this, as well as the Winsock reset command. Possibly TCP\IP stack corruption? You could try a rebuild: It cannot ping the router or the DHCP server. The laptop cannot communicate with anything but on the network so I'm logging onto the laptop with cached credentials. The problem is not at the server end - other devices working fine /releasing and /renewing DHCP addresses from server so it is at the laptop end. The scope is fine ~100 addresses still in the pool and unleased. The DHCP server is the domain controller. What's your DHCP Server and scope? Is it handled by a router or by a server? I don't have another router with which to test this. There were no configuration changes made that I am aware of: I finished working Thursday evening, closed the laptop lid to put it into sleep mode, came back in this morning and had no connectivity The card has worked flawlessly since laptop was bought six months ago. I know these are simple steps for most IT folks, but it never hurts to start with the basics. I hope this at least helps you get started. The antenna may be problematic, or there is interference from an outside source. If this is the case, let me know and I post further troubleshooting tips here. If not, then it is not communicating with the WAP correctly. Once you have setup the static on the card, go check the Wireless Access Point to see if the laptop shows up in the device list.I have had a few small switches suddenly quit moving data through due to a minor power interruption and have had to pull the power plug out (hard reset them) to get them running correctly again. It could prove if the problem is local to the laptop or to your network. If all is good there, try connecting somewhere else, even another network, like at a coffee shop or the like.This is why everything appears to be correct in the laptop, but you get no replies. It could be a bad cable, or port in the device on one end of the other. First check to see if you have a link light on both the Laptop and the Switch/Hub/Router (whatever is at the other end of the physical cable).Without knowing if this is a a wired or wireless connection, I will throw a couple of things out to check. As with any network related error troubleshooting can be a quick or painful process, depending on what your overall layout is in terms of infrastructure.
